I believe x = 2 hope this helps good luck!
They will be forming a right triangle.
long leg is the height of Lyra. 22 meters high from the entrance.
short leg is the distance of Donna. 50 meters from the entrance.
We need to solve for the hypotenuse or the range of communication.
a² + b² = c²
22² + 50² = c²
484 + 2500 = c²
2,984 = c²
√2,984 = √c²
54.63 = c
The range of communication for the two radios is 55 meters.
<span>
3x + 2y = 11</span>
<span />2(7x - y) = 2(3)
14x-2y=6
Adding both equations<span>
3x + 2y = 11</span>
<span>14x-2y=6</span>
<span>17x=17</span>
<span>x=1</span>
<span>substitute x = 1 in any equation</span>
<span>3(1) + 2y = 11</span>
<span>2y = 8</span>
<span>y = 4</span>
<span>Solution: x=1 y=4</span>
If A is the buying value & B the selling value, then the increase =
Increase = (B-A)/A = (1.15 - 0.87)/0.87 = 0.3218 or 31.18%
